Charger for mobile phone operating principle

The principle of operation is simple pulse chargers. First AC mains voltage of 220 V DC voltage is rectified to 300,310 in further using a transistor switch or a special chip, this voltage is converted into pulses with a frequency of tens or hundreds of kilohertz and fed to the primary winding of the transformer with a ferrite core (FT). This requires the presence of two coils, and alternating current, which will create a non-static electromagnetic field. The first coil is disposed at the transmitter and is connected to the network. Some features require account Microsoft, connect to Wi-Fi / data network and subscription. Services may apply. Principle: AC mains voltage is rectified to DC 300,310 B and further via the transistor switch is converted into pulses of a frequency of hundreds of kHz which are supplied to the primary winding of the transformer (ferrite) in the secondary winding (circuit) is mounted rectifier and smoothing filter, as a result we get DC voltage 5V at 350mA load current. The principle of operation of the circuit automatically disconnect the charger in the event of overvoltage due to lack of load collected on the second half of the operational amplifier A1.2 is the same.

Phone charger

The idea of ​​using GSM communication channel in order to security alarm system is not new. There are many expensive foreign-made industrial systems inaccessible to the mass consumer. What is the capacity of the battery and how it mean? Well, we all know that for any smartphone, tablet, or the player need the battery. With the advent of human life technical devices associated weight problems. To work with a particular device needs a power source.

Mobile phone chargers

Chargers can be divided into two broad categories: transformers and pulse. The first type of chargers in our market is now rare, because in spite of the very high degree of reliability, operation hampered his rather large size and weight of the device.
